Abstract
The invention discloses a kind of overlay film type extruded polystyrene board, including extruded polystyrene board substrate and the functional film for being adhered to substrate surface, wherein functional film is for raw material with graphene oxide or derivatives thereof, forms a film to obtain by self assembly.
Description
Technical field
The present invention relates to extruded polystyrene board technical field, more particularly to a kind of overlay film type extruded polystyrene board and its preparation side
Method.
Background technology
Extruded sheet is to be aided with polymer while mixing is heated with polystyrene resin, injecting catalyst, then extrusion molding
The rigid foam plate of continuity closed-cell foam is extruded, it is independent closed bubble structure that it is internal, is that one kind has height
Resistance to compression, water absorption rate are low, moisture-proof, airtight, light, corrosion-resistant, super anti-aging（Long-time service is almost without aging）, thermal conductivity factor it is low
Deng the environment protecting thermal insulating material of excellent properties, it is widely used in dry wall thermal insulating, flat concrete roof and steel-structure roof
Insulation, under cryopreservation ground, low-temperature floor radiant heating heating pipe, the field such as parking platform, airfield runway, highway
Moisture-proof insulation, controls ground frost heave, is construction industry is quality-high and inexpensive, quality is all good heat-insulated, barrier material.
Since XPS plate surface is smooth, stickup property and adhesion are poor, more demanding to construction quality, are actually using
During be easy to the problems such as slip layer, bonding failure occur, cause its application to be restricted, at present common surface treatment method
For mechanical wharf's pavement quality, under external force by styrofoam surface roughening, to increase its surface adhesion, but this processing
Method can cause sheet deformation, cause surface irregularity, exert an adverse impact for the construction in later stage.
The content of the invention
A kind of the defects of present invention is in order to make up prior art, there is provided overlay film type extruded polystyrene board and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of overlay film type extruded polystyrene board, including extruded polystyrene board substrate and the functional film for being adhered to substrate surface, it is described
Functional film be for raw material with graphene oxide or derivatives thereof, form a film to obtain by self assembly.
The graphene oxide is prepared using Humers methods.
The graphene oxide derivative is carboxylated graphene oxide or sulfonic group graphene oxide.
A kind of preparation method of overlay film type extruded polystyrene board, comprises the following steps：
（1）Extruded polystyrene board base-plate cleaning is clean, and holding surface dried and clean, processing metacoxal plate is put into reaction vessel,
At 35 DEG C 30-50min, after treatment discharging are handled with methanol steam；
（2）By graphene oxide or derivatives thereof ultrasonic disperse in decentralized medium, the oxidation stone that concentration is 0.5-5mg/mL is obtained
Black alkene or derivatives thereof solution, resulting solution are put into reaction tank, are heated to 65-80 DEG C, then rapidly will be through step（1）Processing
Substrate afterwards is immersed in graphene oxide or derivatives thereof solution, and constant temperature stands 30min-2h, processing knot under the conditions of 65-80 DEG C
Substrate is taken out after beam, drying after washing with water 2-3 times, up to the styrofoam.
The decentralized medium is for water with organic solvent according to 1:The ratio compounding of 0.01-0.25 forms.
The organic solvent is n-butanol, one kind in ethanol, n,N-Dimethylformamide, tetrahydrofuran.
The silane coupling agent of 0.01%-0.05% can also be added in the decentralized medium.
The present invention is self-assembled into film properties using graphene oxide and carries out surface modification to extruded polystyrene board, to improve it
Surface inertness, auxiliary improve its performance in follow-up use, and mechanism of the invention is, first by styrofoam methanol steam
Pre-processed, under the induction wetting removal effect of methanol steam, styrofoam top layer pattern changes, and is formed on surface largely
Micro-nano structure, improve the assembling effect of graphene oxide and its derivative in substrate surface, be finally obtained Quick uniform
Generation directionality is good, matrix adhesive strength is high graphene oxide functional film, styrofoam and other materials after overlay film
The defects of compatibility is greatly improved, slip layer, cracking, aging has also obtained certain improvement, has also widened styrofoam
Use scope, graphene oxide film layer have very high reactivity, are more easy to carry out various functions processing, economic value is more
It is high.
